Dbs direct binary search 算法
WebOct 29, 1997 · Abstract: The direct binary search (DBS) algorithm is an iterative method which minimizes a metric of error between the grayscale original and halftone image. This is accomplished by adjusting an initial halftone until a local minimum of the metric is achieved at each pixel. The metric incorporates a model for the human visual system (HVS). WebMay 21, 2012 · Halftoning is an important process to convert a gray scale image into a binary image with black and white pixels. The clipping-free DBS (Direct Binary Search)-based halftoning is one of the ...
